SUMMARY
When using Konsole in a wayland KDE session and trying to do this with SSH, I encounter this error:

"Could not open a connection to your authentication agent."

Turns out that the SSH_AUTH_SOCK env var is not set. This used to be always set under X11, but under Wayland that does not always seem to work. I am pretty sure in a previous session I did have working SSH under Wayland, so maybe this is some non-deterministic condition related to the exact order in which services start when the session is brought up.


I can see in "systemctl --user status ssh-agent.service" that the agent is running. In the logs I see the following

Okt 29 21:41:20 r-thinktop agent-launch[19682]: dbus-update-activation-environment: setting SSH_AUTH_SOCK=/run/user/1000/openssh_agent
Okt 29 21:41:20 r-thinktop agent-launch[19682]: dbus-update-activation-environment: setting SSH_AGENT_LAUNCHER=openssh
Okt 29 21:41:20 r-thinktop agent-launch[19678]: SSH_AUTH_SOCK=/run/user/1000/openssh_agent; export SSH_AUTH_SOCK;

so it seems that somehow those environment variables are supposed to make their way into the session proper, and that does not seem to (always) work.
